Title: Static converter device for converting a direct voltage to a poly-phase alternating variable frequency voltage
IPC: H02M7/537
Filed: 1962-01-18
Abstract: 972,161. Converting. FIAT S.p.A. Jan. 18, 1962 [Jan. 18, 1961; Dec. 16, 1961], No. 1928/62. Heading H2F. In a static converter for converting direct voltage to variable frequency polyphase alternating voltage, the direct voltage source is switched in turn through the phases of a polyphase output transformer by means of pulses derived from an oscillator feeding a pulse distributer of the digital ring type. As shown, a pulse generator 1, comprising a tunable astable multivibrator, feeds pulses to a scale-of-three counter, comprising bi-stable multivibrators 2, 3 and feedback circuit 5, to energize diode matrix 4 and produce a system of cyclically recurring pulses on lines A, B and C. These pulses are lengthened by monostable multivibrators 9 to half the period of the output frequency and are then applied to transistor power amplifiers 8 connected in series with the arms 6a of a three-phase transformer 6 and a D.C. source 7. In a modified arrangement, Figs. 3, 4 and 5 (not shown), a scale-of-six counter and an extended diode matrix are used to generate a cyclic system of six pulses which are fed via emitter followers to three bi-stable multivibrators so that the outputs from these provide the three-phase control pulses. These pulses are fed via emitter followers and push-pull amplifiers to push-pull power amplifiers whose power outputs are passed to the output transformer through magnetic amplifiers. Waveform and amplitude control is obtained by providing each magnetic amplifier with a control winding to which is applied a voltage obtained by comparing a standard Zener voltage with the voltage obtained by filtering and rectifying the output of the amplifier. Current transformers in series with each of the arms of the output transformer are connected to a gate-type overload circuit which removes the D.C. supply from the scaleof-six counter if the current in any phase exceeds a chosen value.

Title: Process for the propylation of ortho-and para-cresol
IPC: C07C37/14
Filed: 1928-08-30
Abstract: 325,855. Rheinische Kampfer-Fabrik Ges. Oct. 12, 1927, [Convention date]. Divided on 298,600. Propyl and isopropyl o- and p-cresols are produced by heating o- or p-cresol with propylene by splitting off water (such as propyl or isopropyl alcohol or ether) in presence of a solid dehydrating catalyst such as aluminium, thorium, or tungsten oxide or aluminium phosphate, alone or supported on carriers such as pumice, kieselguhr, silica gel, or active charcoal. Other suitable catalysts are bleaching earth, Florida, fuller's and silica earths, dried kaolins and brick clays, and the substances sold under the registered Trade Marks " Frankonit " and " Tonsil " (which are probably hydrosilicates of aluminium and magnesium), and mixtures of anv of these substances. The reaction may be effected in the liquid or vapour phase, and pressure such as 2-20 atmospheres may be employed, for instance in an autoclave. When the liquid phase is employed, the catalyst is distributed through the liquid by stirring. In an example o-cresol vapour and excess of propylene are passed at 250-350‹ over alumina, the condensed reaction product being fractionated to obtain the individual compounds, which include (a) " ortho-tnymol " (2-oxy-1-methyl-3-isopropylbenzene) boiling at 225-226‹ whose phenyl urethane melts at 159-160‹ C. ; (b) " alpha-metaisocymophenol " (2-oxy-1-methyl - 3 - isopropylbenzene) boiling at 231‹ C., whose benzoyl compound melts at 73‹ C.; (c) a small quantity of carvacrol which forms a phenyl-urethane of melting point 140‹ C.; these compounds being obtainable by forming and then saponifying the derivatives mentioned. A mixture of dipropyl o-cresols remains as a residue in the still. In another example p-cresol vapour and propylene are passed over thorium oxide alone or upon pumice, or of aluminium phosphate on active charcoal, or brick clay or fuller's earth in pieces, the product being fractionated to obtain " parathymol " (4-oxy-1-methyl-3-isopropyl-benzene), a small quantity of 4 - oxy - 1 - methyl-2-isopropylbenzene, and a residue in the still consisting of depropylated p-cresols. The Specification as open to inspection under Sect. 91 (3) (a) states that acids and anhydrides such as sulphuric, phosphoric and sulphonic acids and phosphoric anhydride and also anhydrous zinc and magnesium chlorides may be used as the catalyst. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in dynamometer excitation control systems
IPC: G01M15/04
Filed: 1942-02-20
Abstract: 554,349. Exciting dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 20, 1942, No. 2269. [Class 35] [Also in Group XIX] A dynamometer 14 of eddy current swinging carcase type, is excited so that its torque-speed curve can be matched to that of the load which will be driven by the engine 12 to be tested. Dynamometer field coil 20 is supplied by the armature 17 of an exciter 19 driven by the engine shaft 13, or at a proportionate speed. Its field coil 25 is supplied, in series, by a constant potential from divider 26 across source 24, and by the armature 16 of a second exciter 18 running at the same or a proportionate speed and excited by constant source 24. The exciters 18, 19 are worked in the unsaturated condition so that their output is proportional to their speed. As a result the dynamometer excitation-speed curve has both linear and quadratic components ; when switch 21 is put in the middle position potential divider 21a across source 24 adds a constant component to the output from armature 17. When switch 21 is in the right-hand position only a constant component is left. The various components can be adjusted by resistances 30, 27, 22 and 23, and by switch 31 the quadratic component can be eliminated. In a modification, (i) an amplifier, such as a motor-generator set with a generator of the cross-field type described in Specification 539,835, or an electronic amplifier, is interposed between armature 17 and coil 20, (ii) the potential divider 26 and armature 16 supply separate field coils in exciter 19, (iii) a potential divider across source 24 supplies a constant excitation to a separate field coil in the dynamometer. Any power law between the first and second can be approximated to, by adjusting the three components of the excitation. If the exciters are small, as when an amplifier is used, they need not be cradled with the dynamometer.

Abstract: 1,177,758. Continuous casting-machines; rolling. GERMANY, DEFENCE, MINISTER OF. 17 Jan., 1967 [8 Feb., 1966; 31 Aug., 1966], No. 2398/67. Headings B3F and B3M. In a continuous casting of sheet or strip material in a roller casting apparatus, of alloys that undergo meta-saturation and/or dispersion hardening upon rapid cooling from the molten state, the molten alloy is introduced to the inside of a hollow rotating roller 3 just in front of a second roller 4 extending along the hollow roller 3 and rotating by its contact with the hollow roller 3 or the molten alloy 5. The molten alloy passes through a gap of less than 1 mm. between the two rollers and is rapidly cooled to form a sheet or strip 7 that is fed from the hollow roller 3 by an ejector 13. The deadweight of the roller 4 acts on the alloy and the gap between the rollers is controlled as a function of the speed of rotation of roller 3, the viscosity of the melt 5, and the pressure by which the roller 4 is applied, all of which factors may be varied. The rollers 3 and 4 are laterally aligned by a forked arm 8, or alternatively, or additionally, by a forked arm 8<SP>1</SP> incorporating a shock absorber 12. Either or both of the rollers 3 and 4 may be provided with cooling means. A meta-saturation alloy used may be a binary alloy of aluminium with Cr, Fe, Mn, W, V, Ti or Mo. The addition of silicon to the binary alloy produces the dispersion hardening effect. The meta-saturation and dispersion hardening is also achieved in a Cu-Th-B alloy. A particularly suitable alloy for casting as above described is the eutectic alloy of aluminium and silicon. Another suitable class of alloys is one having at least 70% magnesium and specified quantities Mn, Al, Zn, Ag, Bi, Li, Sn, Zr, Th, Si, Rare earth metals, Ge, Sb, Co, Pb, Cd. Metasaturation is achieved by cooling the molten alloy at the rate of 10<SP>4</SP>‹ C. per second.
